Inverter KACO Powador 14.0 TL3 INT

Imagine perfect grid current - the kind you get from large-scale power plants - but from decentralised renewable sources. The Powador 10.0 TL3 to 14.0 TL3 units combine KACO new energy's many years of experience in developing transformerless units with the requirement for perfect grid feed-in. Since they are true three-phase units, they provide high-quality, sinusoidal alternating current with a 120-degree phase shift. These inverters give you extreme flexibility in designing your PV system. They operate using two separate MPP trackers that can handle completely asymmetric loads to allow for optimum adjustment.

Each tracker is able to process all of the AC output. This allows for all typical requirements of complex designs to be fulfilled; on the one hand, for example, full configuration of an east / west-facing roof (symmetrical load) or, on the other hand, the regular configuration of a south-facing roof without having to dispense with the solar yield of a dormer (asymmetrical load). The MPP trackers can also be connected in parallel. Installation costs less when strings need to be combined before the inverter. The peak efficiency is an impressive 98 %, but the TL3 realises a very high partial load efficiency in the lower power ranges thanks to the innovative solution for the design and control of the inverter bridge: Even at just 5 % rated power they operate at 95 % efficiency. Cooling is provided by demand-driven fans that are aimed directly at the temperature sensitive components.
